JAMES VILLIAMS, OF LAYTONVlLLE, MARYLAND.

FEATHERING PADDLE -WHEEL.

SPECIFICATION forming part of Letters Patent No. 310,350, dated January 6, 1885.

Application filed May 9,1884. (Nomcdeh) I0 all whom, it may concern.-

Be it known that I, JAMES WVILLIAMs, of Laytonville, in the county of Montgomery and State of Maryland, have invented a new and useful Improvement in Feathering Paddle-Wheels, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, forming part of this specification.

This invent-ion relates to feathering paddlewheels which are formed with rotary paddles supported on radial shafts and operated by cams located within the wheel-hub.

The invention consists of the construction and arrangement of parts, hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of my improved feathering paddle-wheel, partly broke1 away. Fig. 2 is an inside view of the wheel-hub, looking fromthe side ofthe wheel opposite to that shown in Fig. 1. Fig. 3 is a sectio. of the wheel and supportingframe, cutting the axle longitudinally on line 00 x of Fig. 1; and Figs. 4, 5, and 6 are detail views. I

A indicates the frame-work of the wheel, in which are j ournaled radial shafts B, carrying paddles O. The inner ends of the shafts extend through suitable openings or bearings in the hollow cylindrical hubD, and are provided with double T-heads E, each of which consists of two buttons, 6 e, of rectangular shape, which are secured to the shaft at right angles to each other. The buttons are formed with double convex sides to facilitate their rotation within the cylinder, and to adapt their ends to be readily engaged by the cams F. The cams F consist of two curved strips, ff, secured to the periphery of a drum, G, which is keyed to the stud or axle H, on which the wheel rotates. The strip f extends nearly three-fourths around the drum, and is secured in contact with its peripheral surface by supports 9, while the strip f occupies the remaining portion of the circumference, and is supported by posts at a distance from the surface of the drum equal to the thickness of strip f. The stripsfj are in the same plane with each other, and their meeting ends h h are beveled from each other. hen the drum is placed in the cylindrical hub, the cams F are at one side of the plane of the radial shafts and in contact with the buttons 0 e. The strip f, being in the same circle with the buttons 6, will rest against the sides of said buttons, while the ends of buttons 6 will project between said strip and the cylinder 1). The shafts carrying the buttons in engagement with the strip f will be firmly held thereby from rotating, and the paddles G, being secured to the shafts in the same planewith the buttons 6, will beheld in feathering position. At the same time the strip f, being in the same circle with the buttons 6, which are adjacent thereto, will rest against the sides of said buttons, while the ends of the buttons 0 will project between the strip f and the drum. The buttons 6, which are in engagement with the strip f, will be at right angles to the buttons 6 in engagement with the strip f. The strip f thus has the effect of turning the paddles one-quarter of a revolution from feathering position to working position. The number of paddles in working position at a time will thus depend upon the length of the strip or cam f. The ends of the buttons are adapted to strike against the ends of the cams as the wheel revolves, causing the shafts to be rotated one-quarter of a revolution by each cam, or one-half a revolution in each revolution of the wheel. The cylinder of the hub is closed at one end by a head, I, which has a journal, J, thereon, which is supported in a bearing, K, in the head-block L. This head-block serves to support the stud or axle H, and to facilitate putting the wheel together and into the frame M the said head-block is made removable from frame M. The block is formed with lugs N, which slide in ways 0, formed in the frame M, and the lugs are confined in said ways by buttons P, which are turned over the lugs after the latter are in place. The opposite end of the cylinderD is closed bya head, Q, which has a recess or bearing, R, on its inner side to receive the end of the stud H, and the outer side of the head Q is formed with a journal, S, which rests and rotates in the frame M.

M is a pin for securing the drum G on the stud H.
